APPARATUS FOR ATOL'IIZING HYDROCARBON FUELS.

Application filed. August 14, 1915.

To all whom it may concern:

Be it known that I, ANTHONY Cos'rA, a citizen of the United States, anda resident of Cleveland, county of Cuyahoga, and State of Ohio," haveinvented a new and useful Improvement in Apparatus for AtomizingHydrocarbon Fuels, of which the following is a specification, theprinciple of the invention being herein explained and the best mode inwhich I. have contemplated applying that principle, so as to distinguishit from other inventions.

The subject of the present invention is a spray nozzle for use inatomizing various liquids and is particularly adapted for use inconnection with a carbureter for securing an efiective atomization ofgasolene, kerosene and the like by means of a column of incoming air. Inthis type of devices it is highly desirable to break up the fuel sofinely that no drops of liquid are drawn up by the incoming air as thesedrops do not actually atomize but are merely scooped up and thus do notgive an intimate intermixture of air and fuel. It is the object of thepresent invention to entirely atomize all of the fuel supplied and toevenly and intimately intermix the same with air,which results in a muchgreater economy of fuel and in securing a greater amount of power from agiven amount of fuel supplied. To the accomplishment of the foregoingand related ends, said invention, then, consists of the meanshereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which theprinciple of the invention may be used.

In said annexed drawing:

Figure 1 is transverse section through my improved spray nozzle taken onthe line 1-1, Fig. 2; and Fig. 2 is a longitudinal section taken on theline 22, Fig. 1.

The general construction of this preferred form of my invention will bereadily seen from these two figures. The device comprises a memberpreferably in the form of a circular disk 1 which is provided with anextension 2 upon one side which is attached to a fuel supply conduit 8.This disk 1 is provided with a central fuel supply pas- Specification ofLetters Patent.

center, these holes 6 being equidistant from the center of such circularchamber.

The disk is adapted to be placed in an upstanding flange 7 or chamber tobe formed in a carbureter of any suitable type through which air will bedrawn into the manifold leading to the engine on which the carbureter isused. Leading from the central. chamber 5 to the air openings 6, are aplurality of radially disposed fuel supply passages 8 which preferablyextend to the transverse and longitudinal center of the opening 6. Thatis, the conduits 9 extending from the ends of such passages, lead to theexact transverse center of such openings, and are so positioned thatthey are mid-way between the top and bottom of these passages 6. In thisway a thin stream of fuel is supplied to the exact center of each of theair passages, and the result will obviously be the formation of aplurality of circular columns of air arising through these air openings.These series of columns of mixed air and fuel will pass up through thecarbureter to the engine.

So small an amount of fuel is applied to each of the air openings thatit will become intimately intermixed with the air passing therethroughand thus the entire rising column of mixed air and gas will be a perfectmixture in which there will be no unatomized fuel.

A plunger 10 is mounted in the top of the disk 1 and is provided at itslower end with a valve 11 adapted when desired to seat upon the upperedge of the conduit 4; thus closing the fuel supply passage. It will beunderstood that other means for throttling the supply of fuel may beused if desired. In actual operation the present invention has givenvery satisfactory results both as to economy and power secured from theengine on which it is used.

Other modes of applying'the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed.

I therefore particularly point out and dis tinctly claim as myinvention 1. A liquid spray nozzle, comprising a member provided with aplurality of parallel air passages therethrough, and a central fuelsupply passage, and a plurality of conduits extending laterally fromsuch fuel passage to the central portion of such parallel passages andsaid conduits lying at sub stantially right angles to the direction ofmovement of air through such passages.

2. A liquid spray nozzle, comprising a member provided with a pluralityof parallel air passages therethrough, and a central fuel supplypassage, and a plurality of conduits extending laterally from such fuelpassage to the transverse centers of such parallel passages, and saidconduits lying at substantially right angles to the direction ofmovement of air through such passages.

3. A liquid spray nozzle, comprising a member provided With a pluralityof paralsaid conduits lying at substantially right angles to thedirection of movement of air I through such passages.

4. A liquid spray nozzle comprising a member provided With a centralfuel supply nozzle and a plurality of equidistant surrounding, parallelair passages therethrough, and conduits extending radially from suchfuel passage to the transverse and longitudinal centers of such parallelpassages, and said conduits lying at substantially right angles to thedirection of movement of air through such passages.

Signed by me, this 11th day of August 1915.
